Once，there lived a wise man.His son，however，had no goal（目标）in life and wasn't happy.

    As the years passed，the man was more and more worried.One day，he handed his son a map and said，"I want you to go and find a treasure."

    The son set out eagerly （急切地）.He travelled really far，across forests and mountains.Finally，he reached the place and began to dig.He dug and dug，but nothing was found.Tired and sad，he decided to go back home.

    On his way back，he noticed dancing birds and beautiful flowers.He met happy farmers in the fields.He found everything nice!

    He got home，and his father asked，"How was your journey to the place？Did you enjoy it？"

    "of course not!I was worried that someone else would find the treasure before I did.But I really enjoyed the journey back home and forgot the pain of not finding the treasure." The son continued to tell his father what he noticed on his way back.

    "Nice things are always there，" the father smiled "My son，I want you to have a goal.If you don't have a goal，you won't set out.But if the goal is the only thing in your mind，you'll miss something nice and won't be happy.So remember：It's important to have a goal in life and enjoy the journey as well".
